TECHNICAL FIELD

Embodiments of the present invention relate to the communications field, and in particular, to a call record synchronization method, a cloud platform, and a terminal.

BACKGROUND

With development of smart wearable products and tablet products, watches and tablet products that can be independently connected to operator networks and can be used to make and answer calls have emerged, for example, watches having a subscriber identity module (Subscriber Identification Module, SIM) card or an embedded SIM (Embedded SIM, eSIM) card and tablet products that support voice over Wireless Fidelity (Voice over WiFi, VoWiFi) transmission. The eSIM card is also referred to as a virtual SIM card or a programmable SIM card. Different from the conventional SIM card, the eSIM card is embedded directly on a chip of a device instead of being separately provided as an independent entity. The device may also be referred to as a terminal or a terminal device.

In view of the development, operators are actively promoting a one-number-multi-card service or a one-number-multi-terminal service. The one-number-multi-card service is a service provided by the operators. Specifically, one number is bound to a plurality of SIM cards (or eSIM cards), and when a call to the phone number is made, terminals with the SIM cards or eSIM cards bound to the number ring simultaneously. The terminals are similar to a plurality of telephone extensions. The one-number-multi-terminal service includes the one-number-multi-card service, and is an extension of the one-number-multi-card service. When a terminal does not support the SIM card or the eSIM card, an effect of the one-number-multi-card service can still be achieved in a WiFi network. For example, VoWiFi is an implementation of the one-number-multi-terminal service.

After a user subscribes to the one-number-multi-card service, a plurality of terminals using the service of multi-card (the SIM card or the eSIM card) with one number can share a primary number. It is assumed that the primary number for which the service is enabled is A. When a call to the user's number A is made, the plurality of terminals of the user ring simultaneously or ring successively, and the user may select any one of the terminals to answer the call. The user may also make a call on any terminal for which the one-number-multi-card service is enabled, and the outgoing call is displayed on a called party as a call from the user's primary number A. This leads to a problem of inconsistent call records on the plurality of terminals for which the one-number-multi-card service is enabled. For example, an incoming call record entry may be displayed on a watch as answered, but may be displayed on a mobile phone as not answered. Therefore, a mechanism for synchronizing a call record among different terminals is required, to ensure that the user views a same call record on different terminals, and can identify on which terminal a call is answered or made.

At present, there are mainly two types of mechanisms for synchronizing a call record among terminals: Bluetooth synchronization and cloud synchronization. In Bluetooth synchronization, when a mobile phone and a watch are within a Bluetooth connection range, and the mobile phone and the watch have been paired via Bluetooth, a call record may be synchronized via Bluetooth. In cloud synchronization, if both a mobile phone and a watch are connected to a cloud synchronization service, call records of terminals using a same cloud account may be synchronized by using the cloud service.

In Bluetooth synchronization, two terminals need to be within a specific range, and once the range exceeds an effective range of Bluetooth transmission, Bluetooth synchronization cannot run. In cloud synchronization, call records of different terminals can be synchronized, and there is no limit to a distance between the terminals. However, the existing solution is simply synchronization from one terminal to another. For example, a user has a plurality of mobile phones, and the plurality of mobile phones have all logged in to a same account. Through cloud synchronization, a call record on one mobile phone can be synchronized to another mobile phone. Call records on different mobile phones exist separately. The user cannot identify call answering or making statuses on the plurality of terminals by using one of the call records, and needs to query a plurality of call records. User experience is poor.

SUMMARY

Embodiments of the present invention provide a call record synchronization method, a cloud platform, and a terminal. A user can use a merged call record to identify call answering or making statuses on a plurality of terminals, without querying a plurality of call records. This improves user experience.

According to a first aspect, a call record synchronization method is provided. A first terminal detects an input operation for requesting to display a call record; and after the first terminal detects the input operation, the first terminal displays a merged call record, where the merged call record is a call record obtained after merging of a call record of the first terminal and a call record of a second terminal, and the merged call record includes a device identifier of the first terminal and/or a device identifier of the second terminal.

In this embodiment of the present invention, the first terminal detects the input operation for requesting to display a call record, and after detecting the input operation, displays the merged call record. The merged call record is the call record obtained after merging of the call record of the first terminal and the call record of the second terminal, and the merged call record includes the device identifier of the first terminal and/or the device identifier of the second terminal. Therefore, by using the merged call record, a user can not only identify a call answering or making status on the first terminal, but also identify a call answering or making status on the second terminal, without querying a plurality of call records. This improves user experience.

In a possible implementation, before the first terminal displays the merged call record, the first terminal receives the call record of the second terminal from the second terminal, where the call record of the second terminal includes at least one piece of call log information of the second terminal; and the first terminal merges the call record of the first terminal and the call record of the second terminal, to obtain the merged call record. According to this implementation, the first terminal may receive the call record of the second terminal directly from the second terminal, and merge the call record of the first terminal and the call record of the second terminal, to obtain the merged call record. This manner is simple and easy to implement.

In a possible implementation, before the first terminal displays the merged call record, the first terminal receives the merged call record from a cloud platform, where the merged call record is a call record obtained after merging, by the cloud platform, of the call record of the first terminal and the call record of the second terminal.

In a possible implementation, before the first terminal displays the merged call record, the first terminal receives the call record of the second terminal from a cloud platform, where the call record of the second terminal includes at least one piece of call log information of the second terminal; and the first terminal merges the call record of the first terminal and the call record of the second terminal, to obtain the merged call record. According to this implementation, the first terminal does not receive the call record of the second terminal directly from the second terminal, but receive the call record of the second terminal from the cloud platform. This manner facilitates centralized management of call records of a large quantity of terminals for the cloud platform, and overcomes a problem that the first terminal and the second terminal cannot transmit a call record by using a Bluetooth communication connection when they are relatively far apart.

In a possible implementation, the first terminal and the second terminal have a same primary number.

In a possible implementation, the merged call record includes a call answering or making record of each of the first terminal and the second terminal.

In a possible implementation, the first terminal is a primary device, and the second terminal is a secondary device; the first terminal receives a call answering or making notification message from the second terminal; and the first terminal displays information in the call answering or making notification of the second terminal. According to this implementation, the primary device can learn that the secondary device has answered or made a call, and notify a user that a call has been answered or made on the secondary device, to alert the user and protect user privacy.

In a possible implementation, the first terminal is a secondary device, and the second terminal is a primary device; the first terminal sends a call answering or making notification message to the second terminal. According to this implementation, the secondary device can notify the primary device that the secondary device has answered or made a call, to alert the user and protect user privacy.

According to a second aspect, a call record synchronization method is provided. A cloud platform receives a call record of each terminal sent by a plurality of terminals, where the call record of each terminal includes at least one piece of call log information of each terminal; the cloud platform merges the call record of each terminal sent by the plurality of terminals, to obtain a merged call record, where the merged call record includes a device identifier of at least one of the plurality of terminals; and the cloud platform sends the merged call record to the at least one of the plurality of terminals.

In this embodiment of the present invention, the cloud platform receives the call record of each terminal sent by the plurality of terminals, merges the call record of each terminal sent by the plurality of terminals, and sends the merged call record to the at least one of the plurality of terminals. The merged call record includes the device identifier of the at least one of the plurality of terminals. Therefore, by using the merged call record, a user can not only identify a call answering or making status on one terminal, but also identify a call answering or making status on another terminal, without querying a plurality of call records. This improves user experience.

In a possible implementation, the cloud platform determines that the plurality of terminals have a same primary number; the cloud platform selects call record entries that belong to the same primary number, from the call record of each terminal sent by the plurality of terminals; and the cloud platform merges the call record entries of each terminal that belong to the same primary number, to obtain the merged call record. According to this implementation, for a plurality of terminals that have subscribed to a one-number-multi-card service, the plurality of terminals having the same primary number are determined first, and then the call record entries that belong to the same primary number are selected from the call record of each terminal sent by the plurality of terminals, to facilitate merging of the call record entries, preventing a waste of processing resources.

In a possible implementation, the merged call record includes a call answering or making record of each of the plurality of terminals.

In a possible implementation, the plurality of terminals include a primary device and a secondary device; the cloud platform receives a call answering or making notification request message from the secondary device; and the cloud platform sends a call answering or making notification message of the secondary device to the primary device. According to this implementation, the secondary device first notifies the cloud platform that the secondary device has answered or made a call, and then the cloud platform notifies the primary device that the secondary device has answered or made a call, to alert the user and protect user privacy.

According to a third aspect, a call record synchronization method is provided. A first terminal sends a call record of the first terminal to a cloud platform, where the call record of the first terminal includes at least one piece of call log information of the first terminal; and the first terminal receives a merged call record from the cloud platform, where the merged call record is a call record obtained after merging of the call record of the first terminal and a call record of a second terminal, and the merged call record includes a device identifier of the first terminal and/or a device identifier of the second terminal.

In this embodiment of the present invention, the merged call record includes the device identifier of the first terminal and/or the device identifier of the second terminal. Therefore, by using the merged call record, a user can not only identify a call answering or making status on one terminal, but also identify a call answering or making status on another terminal, without querying a plurality of call records. This improves user experience.

In a possible implementation, the first terminal and the second terminal have a same primary number.

DESCRIPTION OF EMBODIMENTS

To make the purpose, technical solutions, and advantages of the embodiments of the present invention clearer, the following describes the technical solutions of the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention.

An embodiment of the present invention provides a call record synchronization method. When a user has a plurality of terminals, a call record of each of the plurality of terminals may be synchronized to at least one of the plurality of terminals, and the at least one terminal displays a merged call record. The call record displays call answering or making records of the plurality of terminals and a device identifier of a terminal corresponding to each call record entry.

In one example, when the plurality of terminals perform call record synchronization, a communication connection may be established directly between the plurality of terminals, so that a call record of one terminal is sent to another terminal. For example, the user has two terminals, a mobile phone and a watch. When the mobile phone and the watch are relatively close, the watch may send a call record of the watch to the mobile phone by using a Bluetooth communication connection between the watch and the mobile phone. The Bluetooth communication connection is merely an example. In this embodiment of the present invention, the plurality of terminals may perform call record synchronization in another short-range communication manner.

In another example, when the plurality of terminals perform call record synchronization, a call record of one terminal may be sent to another terminal by forwarding by a third-party server. The third-party server may be but is not limited to a cloud platform. For example, if the plurality of terminals of the user are all connected to the cloud platform and have logged in to a same cloud account, each terminal may upload its own call record to the cloud platform, or may download a call record of another terminal from the cloud platform. To improve user experience, in this embodiment of the present invention, the cloud platform merges the call records of the plurality of terminals, and then sends the merged call record to each terminal, so that the user can query the merged call record on one terminal to know call statuses of the plurality of terminals owned by the user. This improves user experience. For example, the third-party server may alternatively be an instant communication software server such as a WeChat server or a QQ server. To improve user experience, in this embodiment of the present invention, the instant communication software server may also merge the call records of the plurality of terminals, and then sends the merged call record to each terminal, so that the user can query the merged call record on one terminal to know the call statuses of the plurality of terminals owned by the user. This improves user experience.

FIG. 1 is a schematic diagram of an application scenario to which the solution provided in this embodiment of the present invention may be applied. This scenario includes a terminal 101 and a terminal 102. The terminal 101 and the terminal 102 have subscribed to a one-number-multi-card service or a one-number-multi-terminal service, so it is determined that the terminal 101 and the terminal 102 are two terminals of a same user. When the terminal 101 and the terminal 102 are relatively close and a Bluetooth communication connection is established between them, call record synchronization may be performed. For example, a call record of the terminal 101 is sent to the terminal 102, and/or a call record of the terminal 102 is sent to the terminal 101. The terminal 101 and/or the terminal 102 merge/merges call records of the plurality of terminals belonging to the same user, that is, combine/combines a plurality of call records of the plurality of terminals into a merged call record, where the merged call record includes device identifiers of the terminals; and then display/displays the merged call record. In this way, it is convenient for the user to view call statuses of the plurality of terminals on one terminal, and user experience is improved. FIG. 1 shows only a case in which both the terminal 101 and the terminal 102 are mobile phones. Actually, device types of the terminal 101 and the terminal 102 may be the same or different. This is not limited in this embodiment of the present invention. For example, the terminal 101 is a mobile phone, and the terminal 102 is a watch.

FIG. 2 is a schematic diagram of another application scenario to which the solution provided in this embodiment of the present invention may be applied. This scenario includes a cloud platform 201, a terminal 202, a terminal 203, a terminal 204, and a terminal 205. The cloud platform 201 includes a cloud server. The cloud server may also be referred to as a cloud host, which includes a plurality of parts, similar to independent hosts, divided on a group of cluster servers, and each server in a cluster has an image of the cloud host. When a hardware fault occurs on one of the machines, a system automatically accesses an image backup on another machine, improving stability and security of the cloud host. It should be noted that the plurality of terminals of the user may be two or more terminals. This is not limited in this embodiment of the present invention. The plurality of terminals of the user may be of a same type, for example, may all be mobile phones, or may be of different types. For example, one is a mobile phone, another one is a tablet computer, and still another is a smartwatch.

In one example, the cloud platform 201 is configured to provide a cloud synchronization service for the plurality of terminals. The terminal 202 and the terminal 203 have logged in to a cloud account 1, and the terminal 204 and the terminal 205 have logged in to a cloud account 2. The terminal 202, the terminal 203, the terminal 204, and the terminal 205 may all upload their own call records to the cloud platform 201 after updating the call records. After receiving the call records of the plurality of terminals, the cloud platform 201 may determine, based on a cloud account logged in to by each terminal, that the terminal 202 and the terminal 203 have logged in to the same cloud account, namely, the cloud account 1, and therefore determine that the terminal 202 and the terminal 203 are two terminals of a same user; and similarly, may determine that the terminal 204 and the terminal 205 have logged in to the same cloud account, namely, the cloud account 2, and therefore determine that the terminal 204 and the terminal 205 are two terminals of a same user. Subsequently, the cloud platform 201 may send a call record of the terminal 203 to the terminal 202, and/or send a call record of the terminal 202 to the terminal 203, and the terminal 202 and/or the terminal 203 merge/merges and display/displays the call records of the plurality of terminals; and the cloud platform 201 may send a call record of the terminal 205 to the terminal 204, and/or send a call record of the terminal 204 to the terminal 205, and the terminal 204 and/or the terminal 205 merge/merges and display/displays the call records of the plurality of terminals. Optionally, the cloud platform 201 may not directly send a call record of one terminal to another terminal, but instead first merge call records of a plurality of terminals belonging to a same user, that is, combine the plurality of call records of the plurality of terminals into a merged call record, where the merged call record includes device identifiers of the terminals; and then send the merged call record to at least one terminal of the user. In this way, it is convenient for the user to view call statuses of the plurality of terminals on one terminal, and user experience is improved.

In this embodiment of the present invention, when the instant communication software server is used to implement call record synchronization among a plurality of terminals of a same user, and for example, the instant communication software server is the WeChat server, the WeChat server may determine a plurality of terminals that have logged in to a same WeChat account as a plurality of terminals of a same user. A call record synchronization method performed by the instant communication software server is similar to the call record synchronization method performed by the cloud platform, and details are not repeated herein again.

First, the call record synchronization method provided in this embodiment of the present invention is described by using the application scenario shown in FIG. 1 as an example.

With reference to the application scenario shown in FIG. 1, when a user has a plurality of terminals and the plurality of terminals have subscribed to the one-number-multi-card service, if one of the terminals updates a call record, the terminal may synchronize the call record among the plurality of terminals through Bluetooth synchronization.

The plurality of terminals of the user may be a plurality of terminals that have subscribed to the one-number-multi-card service or the one-number-multi-terminal service, but this embodiment of the present invention is not limited thereto. For example, the user has a plurality of mobile phones, and the plurality of mobile phones have not subscribed to the one-number-multi-card service or the one-number-multi-terminal service. In this case, call record synchronization among the plurality of terminals may be implemented according to an instruction of the user by using application programs installed on the mobile phones.

FIG. 3 is a signal flowchart of a call record synchronization method according to an embodiment of the present invention. The figure shows only two terminals, and actually may include more terminals. In this embodiment of the present invention, an example of merging call records of only two terminals is used for description. The method includes the following steps.

Step 301. A first terminal detects an input operation for requesting to display a call record.

In one example, the first terminal may detect whether a user has tapped a preset area on a touchscreen, to determine that the user requests to display a call record.

Optionally, the first terminal and a second terminal have a same primary number.

Step 302. After the first terminal detects the input operation, the first terminal displays a merged call record, where the merged call record is a call record obtained after merging of a call record of the first terminal and a call record of a second terminal, and the merged call record includes a device identifier of the first terminal and/or a device identifier of the second terminal.

Optionally, the merged call record includes a call answering or making record of each of the first terminal and the second terminal.

In one example, the merged call record may be displayed in a two-level manner. To be specific, some information of the call record is first displayed. For example, in a call record entry, only an incoming or outgoing number identifier and time information are displayed. When the user taps an area in which the call record entry is located on the touchscreen or an extended display identifier, all information of the call record entry is displayed. The all information includes the device identifier of the first terminal and/or the device identifier of the second terminal, and may also include information such as a home location.

In this embodiment of the present invention, the first terminal detects the input operation for requesting to display a call record, and after detecting the input operation, displays the merged call record. The merged call record is the call record obtained after merging of the call record of the first terminal and the call record of the second terminal, and the merged call record includes the device identifier of the first terminal and/or the device identifier of the second terminal. Therefore, by using the merged call record, the user can not only identify a call answering or making status on the first terminal, but also identify a call answering or making status on the second terminal, without querying a plurality of call records. This improves user experience.

FIG. 4 is a signal flowchart of another call record synchronization method according to an embodiment of the present invention. Based on step 301 and step 302, before step 302, the method further includes the following steps.

Step 3011. The first terminal receives the call record of the second terminal from the second terminal, where the call record of the second terminal includes at least one piece of call log information of the second terminal.

In one example, the call record of the second terminal is actually a call record list including a plurality of pieces of call log information. During call record synchronization, the second terminal may send the entire call record list to the first terminal, or may send only newly-generated call log information to the first terminal.

Step 3012. The first terminal merges the call record of the first terminal and the call record of the second terminal, to obtain the merged call record.

Merging may be but is not limited to combining the call records of the two terminals, and the merged call record includes the device identifier of the first terminal and/or the device identifier of the second terminal.

According to this implementation, the first terminal may receive the call record of the second terminal directly from the second terminal, and merge the call record of the first terminal and the call record of the second terminal, to obtain the merged call record. This manner is simple and easy to implement.

FIG. 5 is a signal flowchart of still another call record synchronization method according to an embodiment of the present invention. This method may be based on the application scenario shown in FIG. 2. Based on step 301 and step 302, before step 302, the method further includes the following steps.

Step 3013. The first terminal receives the call record of the second terminal from a cloud platform, where the call record of the second terminal includes at least one piece of call log information of the second terminal.

In one example, when the first terminal and the second terminal are relatively far apart, the second terminal may first send the call record of the second terminal to the cloud platform. Then, the cloud platform sends the call record of the second terminal to the first terminal proactively or according to a download request of the first terminal.

Step 3014. The first terminal merges the call record of the first terminal and the call record of the second terminal, to obtain the merged call record.

Merging may be but is not limited to combining the call records of the two terminals, and the merged call record includes the device identifier of the first terminal and/or the device identifier of the second terminal.

According to this implementation, the first terminal does not receive the call record of the second terminal directly from the second terminal, but receive the call record of the second terminal from the cloud platform. This manner facilitates centralized management of call records of a large quantity of terminals for the cloud platform, and overcomes a problem that the first terminal and the second terminal cannot transmit a call record by using a Bluetooth communication connection when they are relatively far apart.

FIG. 6 is a signal flowchart of an alerting method according to an embodiment of the present invention. A first terminal is a primary device, and a second terminal is a secondary device. The method includes the following steps.

Step 601. The first terminal receives a call answering or making notification message from the second terminal.

Obviously, if the first terminal is the secondary device, and the second terminal is the primary device, the first terminal sends a call answering or making notification message to the second terminal.

Step 602. The first terminal displays information in the call answering or making notification of the second terminal.

According to this implementation, the primary device can learn that the secondary device has answered or made a call, and notify a user that a call has been answered or made on the secondary device, to alert the user and protect user privacy.

It should be noted that the alerting method shown in FIG. 6 may be combined with the foregoing call record synchronization methods. For example, when the first terminal receives the call record of the second terminal from the second terminal, it can be considered that the first terminal receives the call answering or making notification message from the second terminal. The alerting method shown in FIG. 6 may also be implemented separately.

The following describes the call record synchronization method provided in this embodiment of the present invention by using the application scenario shown in FIG. 2 as an example.

With reference to the application scenario shown in FIG. 2, when the user has a plurality of terminals and the plurality of terminals have subscribed to the one-number-multi-card service, if one of the terminals updates a call record, the terminal may first determine whether a Bluetooth communication connection to another terminal is established. If it is determined that a Bluetooth communication connection to another terminal is established, the call record may be synchronized among the plurality of terminals in a Bluetooth synchronization manner. If it is determined that a Bluetooth communication connection to another terminal is not established, the call record may be synchronized among the plurality of terminals in a cloud synchronization manner.

The plurality of terminals of the user may be a plurality of terminals that have subscribed to the one-number-multi-card service or the one-number-multi-terminal service, but this embodiment of the present invention is not limited thereto. For example, the user has a plurality of mobile phones, and the plurality of mobile phones have not subscribed to the one-number-multi-card service or the one-number-multi-terminal service. In this case, the cloud platform may also merge call records of the plurality of mobile phones, to improve user experience.

A person skilled in the art may understand that the application scenarios shown in FIG. 1 and FIG. 2 are merely examples of an application scenario of this embodiment of the present invention, but not a limitation to the application scenario of this embodiment of the present invention.

FIG. 7 is a signal flowchart of still another call record synchronization method according to an embodiment of the present invention. The figure shows only two terminals, and actually may include more terminals. In this embodiment of the present invention, an example of merging call records of only two terminals is used for description. The method includes the following steps.

Step 701. A first terminal and/or a second terminal send/sends a call record of each terminal to a cloud platform, where the call record of each terminal includes at least one piece of call log information of each terminal.

In one example, both the first terminal and the second terminal have logged in to a cloud account, and subscribed to a one-number-multi-card service. When the first terminal and the second terminal ring simultaneously or successively, if a user answers the call by using the first terminal instead of the second terminal, the second terminal displays prompt information of the missed call, and generates a call record entry. At this time, the second terminal may immediately send its call record to the cloud platform, and the first terminal needs to wait for the call to end to generate a call record entry, and synchronize a call record to the cloud platform. The first terminal may be a mobile phone, and the second terminal may be a watch. A terminal may send its call record to the cloud platform periodically or after an update of the call record. For example, the first terminal and the second terminal are marked as a terminal 1 and a terminal 2, respectively. A sending interval of a call record may be preset. Each time after the sending interval elapses, the terminal 1 and the terminal 2 send their own call records to the cloud platform, and the cloud platform stores the call records. For another example, a terminal sends its call record to the cloud platform after being powered on, and sends its call record to the cloud platform again after the call record is updated. The update of the call record may include the following: A terminal receives a call but does not answer the call, a terminal receives a call and answers the call, or a terminal makes a call.

Optionally, the cloud platform may determine that the first terminal and the second terminal are using the same cloud account or have used the same cloud account, to determine that the plurality of terminals belong to the same user, so that the cloud platform merges call records of the plurality of terminals of the same user. In practice, the cloud platform may store a correspondence between a terminal and a cloud account. Even if the first terminal and/or the second terminal have/has not logged in to the cloud account, the stored correspondence may be used to determine that the first terminal and the second terminal belong to the same user.

Step 702. The cloud platform merges a call record of the first terminal and a call record of the second terminal, to obtain a merged call record, where the call record includes a device identifier of the first terminal and/or a device identifier of the second terminal.

In one example, a manner of merging, by the cloud platform, the call record of each terminal sent by the plurality of terminals may be combining the call records of the plurality of terminals. For example, referring to a schematic diagram, shown in FIG. 8, of merging call records of a plurality of terminals, incoming call record entries and outgoing call record entries in the call record of each terminal are separately processed. Both the incoming call record entries and the outgoing call record entries may be referred to as call log information. If a call record entry is an incoming call record entry, call record entries, on the plurality of terminals, in which incoming call numbers and times are the same as those of the call record entry are combined into one call record entry, and the combined call record entry includes an answering status on each terminal. If a call record entry is an outgoing call record entry, an outgoing device identifier is added to the outgoing call record entry, and then the call record entry is used as a merged call record entry. For example, combination of incoming call record entries of the plurality of terminals may be shown in Table 1.

TABLE 1 Incoming call Answering number Incoming time status Call record entry 10086 13 hours (h) and Answered of a device 1 20 minutes (min) Call record entry 10086 13 hours and 20 Not answered of a device 2 minutes Combined call 10086 13 hours and 20 Answered on record entry minutes the device 1 Not answered on the device 2

A device type of the device 1 is mobile phone, and a device type of the device 2 is watch. FIG. 9 is a schematic diagram of a display of a call record according to an embodiment of the present invention. As can be seen from FIG. 9, the combined incoming call record provides one call record entry for one incoming call, and the combined incoming call record entry records answering statuses on a plurality of terminals. In FIG. 9, 901 and 902 represent device types of the terminals corresponding to the call record entry, and 904 and 905 represent the answering statuses on the terminals corresponding to the call record entry. 903 indicates that the call is not answered on a watch, and 904 indicates that the call has been answered on a mobile phone. Because the call record entry includes device identifiers of the terminals, a user can identify, based on the call record entry, a terminal on which the user answers the call. The process is simple and clear, and delivers good user experience.

In addition, as can be seen from FIG. 8, an outgoing call record entry 2 indicates a call made by the device 1, and an outgoing call record entry 3 indicates a call made by the device 2. In other words, the merged call record includes both an outgoing call status of the device 1 and an outgoing call status of the device 2. The merged call record includes an outgoing call status of each of the plurality of terminals owned by the user. The merged call record is all-inclusive, keeping the user from querying the call record of each terminal one by one, and delivering good user experience. Referring to FIG. 9, 903 represents a device type of a terminal corresponding to a call record entry, and 906 indicates that the terminal corresponding to the call record entry made a call.

In another example, the cloud platform determines that the plurality of terminals have a same primary number. The cloud platform selects call record entries that belong to the same primary number, from the call record of each terminal sent by the plurality of terminals. For example, after the selection, a call record of the device 1 is listed in Table 2, and a call record of the device 2 is listed in Table 3. The cloud platform merges the call record entries of each terminal that belong to the same primary number, to obtain the merged call record. For example, a merged call record of a primary number A is listed in Table 4.

TABLE 2 Call record Whether Primary Cloud entry answered Device number account identifier Type or not identifier Primary Cloud Call record Incoming Yes Device 1 number A account 1 entry 1 Primary Cloud Call record Outgoing Device 1 number A account 1 entry 2

As can be seen from Table 2, after the call record selection based on the primary number, the call record of the device 1 includes only call record entries of the primary number A.

TABLE 3 Call record Whether Primary Cloud entry answered Device number account identifier Type or not identifier Primary Cloud Call record Incoming No Device 2 number A account 1 entry 1 Primary Cloud Call record Outgoing Device 2 number A account 1 entry 3

As can be seen from Table 3, after the call record selection based on the primary number, the call record of the device 2 includes only call record entries of the primary number A.

TABLE 4 Answering device Call record entry (whether answered Outgoing identifier Type or not) device Call record entry 1 Incoming Device 1 (yes) Call record entry 2 Outgoing Device 1 Call record entry 1 Incoming Device 2 (no) Call record entry 3 Outgoing Device 2

As can be seen from Table 4, the merged call record includes only the call records of the primary number A of the device 1 and the device 2.

In one example, the merged call record includes a call answering or making record of each of the plurality of terminals.

Step 703. The cloud platform sends the merged call record to the first terminal and/or the second terminal.

A terminal may display the merged call record. In one example, a user interface (User Interface, UI) design of a merged call record on a mobile phone is shown in FIG. 10. Referring to FIG. 10, call record entries may be vertically displayed on a display screen of the mobile phone. Each call record entry includes an incoming or outgoing call status identifier 1001, an incoming or outgoing call number identifier 1002, a device identifier 1003, a home location identifier 1004, a call record entry generation time identifier 1005, and a ringing duration identifier or call duration identifier 1006. A first call record entry is used as an example. “x” indicates that an incoming call is not answered, “Peter Smart” indicates an identity of a user of an incoming call number, “Pad” means that the device identifier indicates that a device corresponding to the call record entry is a tablet computer, “Beijing CMCC” means that the home location identifier indicates that a home location is Beijing, “16:40” means that the call record entry generation time identifier indicates that the call record entry is generated at 16:40, and “Rang 2 sec” means that the ringing duration identifier indicates that ringing duration is 2 seconds.

FIG. 11 is a signal flowchart of still another call record synchronization method according to an embodiment of the present invention. Based on the embodiment shown in FIG. 7, a plurality of terminals are classified into a primary device and a secondary device. For example, among two terminals, one is the primary device, and the other one is the secondary device; or among at least three terminals, one is the primary device, and the others are secondary devices. In this embodiment of the present invention, only two terminals are used as an example for description. A first terminal is the primary device, and a second terminal is the secondary device. The method not only includes steps 701 to 703, but also includes the following steps.

Step 704. The second terminal sends a call answering or making notification message to the first terminal.

In one example, when answering or making a call, the second terminal sends the call answering or making notification message to the first terminal by using a Bluetooth communication connection.

In another example, when answering or making a call, the second terminal first determines whether a Bluetooth communication connection to the first terminal is established, and if determining that the Bluetooth communication connection to the first terminal is established, sends a call answering or making notification request message to the cloud platform. The request message may carry a device identifier of the second terminal and/or a device identifier of the first terminal. The cloud platform pushes the call answering or making notification message to the first terminal. The notification message may be but is not limited to an SMS message push notification. Optionally, the request message carries only the device identifier of the second terminal, and the cloud platform may query the first terminal based on a table, stored by the cloud platform, of a correspondence between the primary device and the secondary device, and then sends the call answering or making notification message of the second terminal to the first terminal. Alternatively, the request message not only carries the device identifier of the second terminal, but also carries the device identifier of the first terminal, and the cloud platform may send the call answering or making notification message of the second terminal to the first terminal based on the device identifier of the first terminal.

Step 705. The first terminal displays information in the call answering or making notification of the second terminal.

The first terminal, namely the primary device, may display the information in the call answering or making notification of the secondary device in a plurality of manners.

FIG. 12 is a schematic diagram of receiving, by a primary device in a lock screen state, a call answering notification of a secondary device according to an embodiment of the present invention. Referring to FIG. 12, notification information displayed on the primary device may include a device identifier 1201 (for example, a tablet computer), an answering status 1202 (for example, answered or rejected), a time 1203 (for example, just now) when a call is answered, an incoming call number 1204 (for example, 17600045955), and ring duration 1205 (for example, rang 5 sec). It can be understood that the primary device may display the notification information on a display screen, or may play the notification information by using a speaker or an earpiece.

FIG. 13 is a schematic diagram of indicating, by a system notification bar and an SMS message on a primary device, reception of a call answering notification of a secondary device according to an embodiment of the present invention. Referring to FIG. 13, a left figure is a schematic diagram of indicating, by the system notification bar on the primary device, reception of the call answering notification of the secondary device, where a part indicated by 1301 is the call answering notification, displayed in the system notification bar, of the secondary device; and a right figure is a schematic diagram of indicating, by the SMS message on the primary device, reception of the call answering notification of the secondary device, where a part indicated by 1302 is the call answering notification, displayed in the SMS message, of the secondary device. In this embodiment of the present invention, a manner of displaying the notification information to a user by the primary device is not specifically limited.

It should be noted that a sequence for performing steps 701 to 703 and steps 704 and 705 is not limited. Steps 701 to 703 may be performed before steps 704 and 705 are performed, or steps 704 and 705 may be performed before steps 701 to 703 are performed, or steps 701 to 703 and steps 704 and 705 may be performed simultaneously. In addition, steps 704 and 705 may separately constitute a solution for preventing problems of theft of the secondary device and privacy leakage.
